“…Its drawbacks, as well as those of another interpolation practice due to Schneider & Raw (1987), have been analysed by Deng et al (1994a,b), where the so-called consistent physical interpolation (CPI) method is proposed. The application of the CPI to unsteady laminar flows has been further developed by Deng et al (1994a) for airfoil problems and extended to turbulent flow by Guilmineau et al (1997a).…”

The aerodynamic characteristics of a ski jumper model in various postures are analyzed using a commercial computational fluid dynamics tool. The purpose of this study is to understand the aerodynamic characteristics of ski jumping. The range of flying postures for ski jumpers is determined as widely as possible to simulate the optimal flight position of ski jumpers. The computational results are in good agreement with experimental results. The aerodynamic characteristics are influenced by the hip and body angles of the ski jumper model during the flight. The lift-to-drag ratio of ski jumpers is increased as hip angle increases. However, as the hip angle increases, the region of the angle of attack becomes restricted for stable flight. The augmentation of the body angle can enhance the most favorable angle of attack, because the body angle is likely to result in a cambered airfoil. In conclusion, the ski jumper should maintain a high hip angle with an angle of attack that stabilizes the flight condition, to improve flight distance.

“…For the reasons mentioned above flows aver airfoils are often used as benchmark cases for testing the performance of transition and turbulence models. A comprehensive review on computations of airfoil flows was given by Guilmineau et al [28]. Experiments for the cases considered here were performed by Coles and Wadcock [29] who provided results for surface-pressure distribution and profiles of mean flow and turbulent stresses at four locations in the boundary layer and in the near wake of the airfoil.…”

Numerical predictions with a differential Reynolds stress closure, which in its original formulation explicitly takes into account possible states of turbulence on the anisotropy-invariant map, are presented. Thus the influence of anisotropy of turbulence on the modeled terms in the governing equations for the Reynolds stresses is accounted for directly. The anisotropy invariant Reynolds stress model (AIRSM) is implemented and validated in different finite-volume codes. The standard wall-function approach is employed as initial step in order to predict simple and complex wall-bounded flows undergoing large separation. Despite the use of simple wall functions, the model performed satisfactory in predicting these flows. The predictions of the AIRSM were also compared with existing Reynolds stress models and it was found that the present model results in improved convergence compared with other models. Numerical issues involved in the implementation and application of the model are also addressed.
